Validate if the date entered (using HTML5 date picker) is older than today's date

Question

In HTML, i'm entering a date (mm/dd/yyyy) using the new HTML 5 date picker:

 <input name="date" type="date">

I want to validate if the date entered is older than today's date

$this_date = $_POST['date'];

if ($this_date is older the today's date) {
    echo 'The date entered must be greater than today's date';
} else {
    echo 'The date is valid!';
}

How do I go about?

Thanks

if (time() > strtotime($_POST['date'])) {
    echo "The date entered must be greater than today's date";
} else {
    echo "The date is valid!";
}

<?php
   $this_date = $_POST['date'];

   if (strtotime($this_date . " 00:00:00") > strtotime(date("m/d/Y 00:00:00"))) {
       echo "The date entered must be greater than today's date";
   } else {
       echo "The date is valid!";
    }
?>

Also, you should check the input from the user for validity using preg_match() or some other techniques.

Be aware that the PHP will handle invalid dates like 02/30/2014. It will evaluate to 03/02/2014.

Here you have the right answer:

$diff = strtotime($_POST['date'])>0? strtotime('Today')-strtotime($_POST['date']):NULL;
$res = $diff>0?"The date is valid!":"The date entered must be greater than today's date";
echo $res;
